Yeah, in the second link I posted there are the basic parts if you scroll down. Just no elbows. I have mine vertically coming from the rubber connector that came with the filter. Except I replaced the connectors with black ones from Amazon. I drilled a few extra holes in the tube to lessen the flow a little.
I couldn't see anything else on the link you posted, but seeing the intake tube definitely sparked my idea so thank you!
